Access model in another qml component

So just define an id (detailRectangle) there and it will be accessible. See my earlier edited post.

So you mean:

in TimelineDeviceDetail.qml

@
//detail
Rectangle {
id: detailRectangle
width: 0
height: 200
color: "#FFFFFF"
radius: 4
anchors.right: parent.right
anchors.rightMargin: 100
opacity: 0.70
anchors.left: timelineLineRectangle.right
anchors.leftMargin: 165
anchors.top: timeslotRow.bottom
anchors.topMargin: 0
visible: true //debugging: make it false

    Text {
        id: euroText

// Component.onCompleted: console.log("euro: " + timeslotmodel.euro)
text: model.euro
anchors.top: parent.top
anchors.topMargin: 20
anchors.left: parent.left
anchors.leftMargin: 20
font.pixelSize: 12
}

    Text {
        id: kwhText

// Component.onCompleted: console.log("kwh: " + timeslotmodel.kwh)
text: model.kwh
anchors.top: parent.top
anchors.topMargin: 20
anchors.horizontalCenter: parent.horizontalCenter
font.pixelSize: 12
}

    Text {
        id: timeText
        text: model.time
        anchors.top: parent.top
        anchors.topMargin: 20
        anchors.right: parent.right
        anchors.rightMargin: 20
        font.pixelSize: 12
    }

//...
@

and int TimelineVertical.qml:

@
Repeater {
id: deviceRepeater
model: timeslotmodel
delegate: TimelineDeviceDetail {}
// Component.onCompleted: console.log("euroValueTest: " + timeslotmodel.euro)
Button {id: deviceImageButton; anchors.verticalCenter: parent.verticalCenter; iconSource: deviceImage; width: 100; height: 100; /onClicked: setVisibleEffect(detailRectangle, deviceItem);/ style: TimelineDeviceButtonStyle{} }

                        }
                    }
                }
            }
        }

         TimelineDeviceDetail {} //set the view where I need it

@

But than I get the same error as before:

qrc:///TimelineDeviceDetail.qml:22:19: Unable to assign [undefined] to QString
qrc:///TimelineDeviceDetail.qml:33:19: Unable to assign [undefined] to QString
qrc:///TimelineDeviceDetail.qml:42:19: Unable to assign [undefined] to QString

I put the code from TimelineDeviceDetail.qml back to TimelineVertical.qml to make it simple. It turned out that it's even there not accessible...

@
Row {
id: deviceRow

                        Repeater {
                            id: deviceRepeater

                            Button {id: deviceImageButton; anchors.verticalCenter: parent.verticalCenter; iconSource: deviceImage; width: 100; height: 100; onClicked: setVisibleEffect(detailRectangle, deviceItem); style: TimelineDeviceButtonStyle{} }
                        }

If you define delegate in same file then you will need to encapsulate it in Component.

Going to the previous, you have again added TimelineDeviceDetail there. Please remove it or you will get the same errors. Please refer my earlier posts.
TimelineDeviceDetail will be accessible using its id even if it is specified in separate file.

Ok thanks for that advise. Can you please tell my if I remove "TimelineDeviceDetail" from "TimelineVertical" how to include the TimelineDeviceDetail in TimelineVertical? Or can you make "will be accessible using its id..." a little bit more clear?

Thanks

Ok. Just revisited the posts. I too got confused. Lots of code here :)
First Why would you want TimelineDeviceDetail outside the delegate as it has already been assigned as delegate to repeater ?

Just created a small example related to above:
@
//TimelineDeviceDetail.qml
import QtQuick 2.3
Rectangle {
id: detailRectangle
y: index*40
width: 300
height: 40
color: "lightgray"
Text {
anchors.centerIn: parent
text: model.euro
}
}

//main.qml
import QtQuick 2.3
Rectangle {
width: 300
height: 180

ListModel {
    id: mymodel
    ListElement {
        euro: "3"
    }
    ListElement {
        euro: "6"
    }
}

Repeater {
    model: mymodel
    delegate: TimelineDeviceDetail {}
}

}
@

Here TimelineDeviceDetail is able to access the model role(euro).
Now can you format your question and requirements according to above example so it will be easier for me to understand?

That's a good idea to simplify that. Did you compile the example?

I get the following error:

@
qrc:///TestTimeline.qml:12: ReferenceError: model is not defined
@

Test.qml:

@
import QtQuick 2.3
import QtQuick.Controls 1.2
import QtQuick.Layouts 1.1

Rectangle {
id: rectangle1
anchors.fill: parent

Rectangle {
    width: 300
    height: 180

    ListModel {
        id: mymodel
        ListElement {
            euro: "3"
        }
        ListElement {
            euro: "6"
        }
    }

    Repeater {
        model: mymodel
        delegate: TestTimeline {}

        Text {
            text: euro
        }
    }
}

}
@

TestTimeline.qml:

@
import QtQuick 2.3
import QtQuick.Controls 1.2
import QtQuick.Layouts 1.1

Rectangle {
id: detailRectangle
width: 300
height: 40
color: "blue"
Text {
anchors.centerIn: parent
text: model.euro
}
}
@

I made some little changes on your code.

morker · wrote on 11 Dec 2014, 10:51

I set up a new project just to test this little example and the same here. Any suggestions?

morker · wrote on 12 Dec 2014, 13:50

I fixed this with JavaScript, probably not this best way but it works for me...

TimleineVertical.qml:

@
Row {
id: deviceRow
spacing: 20

                        Repeater {
                            id: deviceRepeater
                            model: attributes

                            Button {id: deviceImageButton;
                                anchors.verticalCenter: parent.verticalCenter;
                                iconSource: deviceImage;
                                width: 100;
                                height: 100;
                                onClicked: setVisibleDetail(detailRectangle, deviceItem), setTest(euro, kwh, time, euroText, kwhText, timeText)

                                style: TimelineDeviceButtonStyle{} }

                        }

@

JavaScript to set the values from the model for the text element:

@
function setTest(euro, kwh, time, euroText, kwhText, timeText) {
euroText.text = euro;
kwhText.text = kwh;
timeText.text = time;
}
@

Text element:

@
Text {
id: euroText
anchors.top: parent.top
anchors.topMargin: 30
anchors.left: parent.left
anchors.leftMargin: 20
font.pixelSize: 12
}
@
